* headers: avoid bareword attributesEric Blake2017-08-172-15/+15
| | | | | | | | | Always use the __-decorated form of an attribute name in public headers, as the bareword form is in the user's namespace, and we don't want compilation to break just because the user defines the bareword to mean something else. Signed-off-by: Eric Blake <eblake@redhat.com>

* Don't fetch command line options without semi-hostingYao Qi2017-08-091-0/+6
| | | | | | | | | | | | | | | | | Nowadays, the code fetching command line options via semi-hosting are unconditionally pulled in, so that the semi-hosting code is still there even I compile with option --specs=nosys.specs. gdb ./aarch64-none-elf/libgloss/aarch64/crt0.o (gdb) disassemble _start 0x0000000000000050 <+80>: ldr x1, 0x128 <_cpu_init_hook+48> 0x0000000000000054 <+84>: mov w0, #0x15 0x0000000000000058 <+88>: hlt #0xf000 This patch fixes this problem by wrapping the code by ARM_RDI_MONITOR. When semi-hosting is not used, set command line options to NULL.
* Fix crt0 overwriting.Tamar Christina2017-08-094-1/+10
| | | | | | | | | | | On AArch64 we currently always link in crt0 regardless of if another one is being provided by something else, like rdimon.a. This was never an issue before as nosys was not supported on AArch64. This updates the specs to supply a different crt0 when a semihosting call is required.

* Proper locking for getchar() and putchar()Sebastian Huber2017-08-071-7/+32
| | | | | | | | | | | | | Add internal inline functions _getchar_unlocked() and _putchar_unlocked() if __CUSTOM_FILE_IO__ is not defined. These functions get _REENT only once. Use them for getchar_unlocked() and putchar_unlocked(). Define getchar() and putchar() to these unlocked internal functions if __SINGLE_THREAD__ is defined, otherwise use the external functions to use proper locking of the FILE object. Assumes that __SINGLE_THREAD__ is not defined if __CYGWIN__ is defined. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

| | | | | | | | | | | | | - Introduce inline helper pthread_convert_abstime. It converts an absolute timespec to a Windows LARGE_INTEGER timestamp, depending on the used clock. - Use this function from pthread_cond_timedwait and semaphore::timedwait - Merge semaphore::_wait and semaphore::_timedwait into single _wait method, taking a LARGER_INTEGER timestamp.

| | | | | | | | | | | | For historical reasons peek_console was calling the functions PeekConsoleInputA and ReadConsoleInputA. However, these functions are not working correctly under at least codepage 65001 (UTF-8) on systems prior to Windows 10. Use PeekConsoleInputW and ReadConsoleInputW instead, which work correctly under all systems and all codepages. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | | | | | | | | | | | | So far we had two functions checking the content of a reparse point, readdir_check_reparse_point in fhandler_disk_file.cc for the sake of readdir, and symlink_info::check_reparse_point for the sake of generic path checking. * Rename check_reparse_point_target helper to check_reparse_point_string and convert to static function. * Create new check_reparse_point_target helper containing the core reparse point checking code * Just call check_reparse_point_target from readdir_check_reparse_point and symlink_info::check_reparse_point and only perform the unique task in those functions.

* Previous patch to support nosys.specs accidentally broke validation specs ↵Tamar Christina2017-07-211-1/+1
| | | | | | | | | | | | because ARM_RDI_MONITOR was never passed to the build rule for crt0. This fixed the compile for nosys and validation specs but nosys won't run because of existing limitations to aarch64's syscalls.c, it requires semihosting to get commandline arguments and heap info without having a fallback method as ARM does.

* arm: Update strcpy.c to use UAL syntax.Ian Tessier via newlib2017-07-201-6/+7
| | | | | | | | | | | | | With this change the arm platform can now be fully compiled with Clang. Tested by comparing the output with GCC 4.8.2, and Clang 4.0, using a variety of arches, big/little endianness, and arm/thumb mode to verify the generated assembly output matches between GCC vs Clang with UAL, and also GCC with UAL vs GCC with non-UAL, for all preprocessor code blocks. The only difference found is an extra nop at the end of the function when compiled with GCC using armv7-a/thumb/little-endian/-O2 compared to Clang. The nop is not emitted when compiled in big-endian mode.
